A Flow describes a collection of fields. It is named after the internal entity type you wish to associate it with. For example, a Flow with a slug of
products will be applied to all product responses in your store.
A Field represents a single field of data (for example a
Product Rating) to be applied to an entity. All Fields have a type (
relationship), a default value and an optional set of validation rules.
An Entry is a specific instance of a Flow, and is associated with a specific instance of an entity (for example, a single product).
